Efficient Heat exchanger with T-type finned tube

Brief Introduction:

he T-type finned high efficient tube is a high-effect intensive heat transfer tube which is rolling milled from plain tubes. There are continuous helical annular T-type tunnel outside the tube surface.

The medium outside the tube forms a series of bubble nucleuses within tunnels during heating process. The bubble nucleuses inflate quickly to full the interior chamber with being heated. The pressure within the bubbles increases quickly, which impels the bubbles to spurt out rapidly from the thin slot of the tube surface（See above drawing）. Big scouring power and some local negative pressure will be produced when the bubbles spurting out. It makes the lower temperature liquid in the vicinity rush into the T-type tunnels. In this way the liquid outside the tubes keeps boiling.

As long as the shell-side medium is relatively clean and of no solid particles or pectin, T-type finned tubes can be used as the heat transfer elements. It can enhance the shell-side boiling heat transfer effect.

1   High heat transfer coefficient.

2  A small difference in temperature can maintain fluids boiling. Therefore, the irreversible loss of heat transfer is reduced.

3    Its price is lower than aluminum porous coating heat transfer tube.

4  The gas and liquid inside the tunnel is turbulent acutely and gas spurt out from the T slot at high speed. Therefore, foul is hardly deposited inside the T-type tunnel and outside the tube. It assures that the equipment can use for a longer time with the heat transfer effect keeping in a higher level.

1  The boiling heat transfer coefficient of T tube is 1.6-3.3 times higher than that of plain tube.

2  A temperature difference of 2-4℃is enough for the cold medium to  boil up.
